hi friends, as title say which exhaust system is quiter and better on r33gtst thanks need help asap.making 290kw.

I've been looking at the same options for my R32 and the Kak system was quieter out of the 2 but still had a nice note above 4k

  • 1 month later...

Slightly off topic but I have just fitted the Kakimoto Regu 06&R to my EVO and the difference in performance and overall exhaust note compared to the unknown Japanese system I previously had is very noticeable. There is virtually no drone at idle/cruise but the system has a phenominal bark when you apply the right foot :thumbsup:

im looking at getting kaki for my car from JJR, heard a few clips on youtube and sounded great, my zorst is way to loud and more suited for track

The Regu 06&R is one of our most popular systems at the moment for street driven vehicles.

You will not be disappointed :thumbsup:

I've got a Kakimoto Regu 06&r on my R34 GTT...

Performance

It is basically silent as stock (idle to 2.5k) and 3k all the way to redline there is a quality growl.

Put it this way everyone who jumps into your car will think you have a stock exhaust (without looking at it lol) before your turbo kicks in...

Looks

I looked at every catback for my car about an year ago prior to purchasing it... HKS/Apexi etc. All did not come up to scratch in terms of finish by comparison to this. Chrome tip as well... its almost silver/gold (the advertising style pics are a little deceiving) in color as well so if you have bronze/gold rims they will match up nicely.

I can record the note from my exhaust to my phone and upload it if theres any interest??

+1 for Kaki Regu 06&R

Have had one of these on my car for about a year now and it's a awesome sounding exhaust. Good at low revs and daily driving, but open's up great when you're giving it heaps.

Have heard from my tuner that the Trust PE II is quiet, because it is quite restrictive.

so it seems the kaki regu 06 is the better choice over the trust pe2 (im guessing both of these exhausts are stainless steal?) ?

i was wondering if someone could also answer this question:

atm i have a HKS hi-power catback, unknown cat, unknown 3" frontpipe... what dB would this roughly be rated at? how much would the kaki reduce the sound by (db) ?

just so i can get a comparison to see if its worth getting the kaki or trust or just staying with the HKS if its not going to change things much

    • So.... the K&N air box thingo was too big, ended up gifting it to a mate, well, by gifting it he actually supplied food and beer at the pub,  which was nice, as it will not sit on a shelf in the garage for the next 10 years I did trim up some of the existing stuff to neaten it all up and gave it some wrinkle paint, unfortunately it currently has a used and abused mish mash of different types of hose clamps, 4 big fat T bolt type (shit), and a few normal clamps of vairing sizes and brands, but..... only until the 6 constant tension black worm clamps that I ordered from EFI solutions turn up next week Currently the current hose clamps are triggering me hard, LOL Is this the final version, probably not, I really want just 2 silicone pieces, a straight bit of silicone from the filter to the MAF is easy and will happen as soon as I head into Just Jap tomorrow, the problematic part is a 30° silicone bend from the MAF to the TB that I can connect the engine breather from the head, I found that there are bulk head fittings for boat bilge pumps that should work, but until I can get a 30° silicone bend the alloy pipe, and the 11ty thousand hose clamps, are there for the foreseeable future 4 hose clamps are golden, 6 are grudgingly acceptable, the 8 currently holding it all together is just taking the piss    I've also ordered 60 more retaining wall blocks for the front yard, I mis-gonculated the height that was required to get above the base of the Photinia's (red robin's) that are the hedge behind the front fence, currently it is 2 blocks high, and about 1/2 a block short, so going 3 blocks high will be above the base of the red robin's, and allow some room for mulch
    • It is the stock air box with the panel filter. Everything else is stock except the exhaust at this point, as I also went back to the cleaned 270cc injectors. I will check the RPM when the IACV is unplugged and report back.
    • As MBS suggested if this is happening when the engine is cold you're going to want to remove the intake air regulator and verify resistance + that the shutter is physically opening and closing. At -20C should be fully open, 20C half open, over 60C fully closed. At 20C should be 70-80 ohms. For AAC valve testing using a Consult cable see if you can raise and lower the idle by commanding more or less AAC duty cycle. Hopefully it's pretty linear as well, shouldn't be like 30% AAC valve is barely idling and 40% is 1500 rpm.
    • Bloody apprentices! 🙄
    • Not sure yet.  Was considering speedtek because it was rated to 800hp, but when I did some research about him I don't think I will go for that🤣 So maybe giken gear set, but I'm afraid it won't be strong enough🙄
